New card in dragons of legend

There is this new card called Mathematician. Here is what he does: When this card is Normal Summoned: You can send 1 Level 4 or lower monster from your Deck to the Graveyard. When this card is destroyed by battle and sent to the Graveyard: You can draw 1 card. I think he is a good card. What do you think of Mathematician?

Mathematician seems like a good card to have in general, though you'd have the usual Bottomless Trap Hole to deal with when you attempt to Summon it. There are also a whole bunch of effects that can just pop him so that you don't get the drawing effect.
